(Los Angeles Times) – The first attempt in the United States to use the CRISPR gene-editing tool against cancer seems safe in the three patients who have had it so far, but it’s too soon to know whether the treatment will improve survival, doctors reported Wednesday. The doctors were able to take immune system cells from the patients’ blood and alter them genetically to help them recognize and fight cancer, with minimal and manageable side effects.
